概覽

AI 產生的概覽

遠端 MCP 伺服器，依公司網域補充 B2B 企業輪廓，提供企業屬性、技術堆疊、意圖與聯絡人資料及信心分數。

可以做什麼
  • 依網域將公司補充為結構化輪廓，包含企業基本資料、技術堆疊、購買意圖訊號、聯絡人資料與信心分數。
  • 可指定需要的屬性類型（firmographic、technographic、intent、contacts）以及必須包含的欄位。
  • 除原始資料外，也會回傳擴編、購買意圖等衍生洞察。
適用情境
適合在業務開發前篩選潛在客戶、銷售通話前調查公司、為行銷活動批次補充公司資料，或了解潛在客戶的技術堆疊與購買意圖訊號時使用。
執行需求
需要遠端 streamable HTTP 端點，不需本機執行環境。需在服務商網站註冊取得 API 金鑰，透過 Authorization Bearer 標頭傳入（Claude Desktop 範例中為 API_KEY 環境變數）。需能連線至服務商主機。
安裝前請注意
API 金鑰是付費憑證，須妥善保管。依用量計費：免費額度 100 次補充，Pro 版每月 49 美元且有超額費用，僅對成功且高信心的補充計費。提交的公司網域會傳送給第三方服務，且各方案有速率限制。

安裝

交給代理程式安裝

把這段提示詞貼上到 Claude Code、Codex、Cursor 等代理程式，或 SourceWeft 對話中。代理程式會讀取該伺服器的安裝指南，先向你展示發布者、端點和登入方式，經你同意後再把它新增到你的客戶端。金鑰不會寫進任何命令。

閱讀 https://sourceweft.com/mcp/io.github.Diego-Costa-Tech%2Flead-enrichment-mcp/install.md，並按其中說明把這個 MCP 伺服器接入我的客戶端。修改任何設定之前，先告訴我它的發布者、端點和登入方式，等我確認。不要把 API 金鑰寫進命令或我會提交的檔案；問我金鑰應從哪裡取得。
